I found myself in Santiago for a few days after heading back from a work trip in Brazil. I didn't think I'd get that much out of the trip aside from getting to see the sights of the city. On a whim, I contacted Geoexpedition to see if I could get some rock climbing in. They were able to accomodate me with less than 24 hours in advance! And it was a personalized tour, it was just me which was awesome! Additionally, I came to Chile woefully underprepared to rock climb, let alone in cooler weather after coming from 90-100 degree Fahrenheit weather in southeast Brazil. Geoexpedition was able to help with that, along with providing me with a harness, shoes, and chalk which I had left in the United States. As far as the climbing aspect, they will be able to accommodate you whether you are a novice, a gym rat such as myself, or a seasoned veteran outdoor climber. They are very friendly and encouraging and will try to gently push you to test your abilities, while making sure you are as safe as the sport will allow. There are multiple climbing areas near Cajon del Maipo so you also have a choice of where you can climb. Top notch. The geology aspect was also amazing. I have a little geotechnical background but am not much of a geologist, but Francisco was able to explain a lot about Santiago's natural history in a way that I could understand, while also pointing out natural features of the region such as the anticlines and synclines that make up the region. All of this was on our way to observe the nearby volcano. The guides, Francisco and Pablo, are very experienced in climbing and mountaineering, and Francisco is a professional geologist. They are super fun to talk to and very easygoing. It's incredibly fun to finish climbing a pitch and enjoy some Mate with them. To sum it up and to stop rambling, I would 10/10 recommend booking this tour. Incredibly personalized and incredibly fun.
